Capacitor multiplier with high multiplication factor for integrated low pass filter of biomedical applications using DTMOS technique

Abstract

In this work, capacitor multiplier circuit is designed for use in biomedical applications. The designed circuit operates with +/- 0.3 V supply voltage at very low quiescent current. The design of the proposed circuit is realized with DTMOS technique by using standard CMOS process. The designed circuit has a high multiplication factor and allows the integration of the capacitance of the low-pass filters required in low-frequency applications such as bio-medicals. At the same time, the proposed circuit has the low power consumption that should be in implantable devices. The proposed circuit is designed with 0.18 mu m TSMC technology in Cadence environment.
